I was unable to dismantle the drive and reach the clutch and as the drive was already 20 years old, Lewmar offered me a special discount for a complete new drive, which I accepted.
Overall, this is the best electrical
drive for a shaft driven steering system, like I have (no cables
, no quadrant, just a set of heavy duty gears as my rudder
is quite huge. It worked perfectly well for all the years. Hydraulic drive may have some advantages, but basically more complicated if you really want a robust and reliable one.
know what they're doing in quality boat
building and design, so should work
well for you.
Best of luck!
